# Wastewater mismanagement in Mexico and Spain > Live situation record from CLSTR: https://clstr.news/situations/wastewater-mismanagement-in-mexico-and-spain > Updated: 2026-09-12T22:54:35.000Z. Sources: 3. Developments: 2. Reports have emerged regarding improper wastewater and sewage management in Mexico and Spain, causing environmental and agricultural concerns. In José María Morelos, Mexico, residents reported that sewage from septic tanks is being dumped into a municipal landfill. Local farmers observed trucks discharging liquid waste that emits a “nauseating odor,” noting that a lack of fencing and surveillance at the site has facilitated this unauthorized activity. In Villanueva del Fresno, Spain, a farmer is contesting the discharge of municipal wastewater onto agricultural land. The resident claims that the sewage network lacks sufficient capacity during heavy rain, leading to overflows that contaminate water used for livestock and irrigation. While the environmental management consortium, Promedio, maintains that the system is functioning normally and that overflows are “authorized relief measures during rainfall,” the farmer reports that the contaminated water has forced the sale of livestock. ## Timeline ### 2026-09-12: Wastewater mismanagement reported in Mexico and Spain Residents in José María Morelos and Villanueva del Fresno report environmental concerns regarding sewage dumping and wastewater overflows affecting local agriculture and sanitation. 3 sources. https://clstr.news/cluster/wastewater-mismanagement-reported-in-mexico-and-spain ### 2026-08-17: Cuautla waste collectors report illegal dumping in ravines Unregulated waste collectors in Cuautla, Morelos, are reportedly dumping trash in ravines to avoid landfill fees, prompting calls for increased municipal oversight. 2 sources. https://clstr.news/cluster/cuautla-waste-collectors-report-illegal-dumping-in-ravines --- Cite as: Wastewater mismanagement in Mexico and Spain.
